brw: Add missing dependency classes to various passes

- brw_lower_3src_null_dest: Allocating a new destination, so include
  INSTRUCTION_DATA_FLOW class.

- brw_lower_alu_restriction: Removing instruction, so include
  INSTRUCTION_IDENTITY.  No details are changed so remove
  INSTRUCTION_DETAIL.

- brw_lower_vgrfs_to_fixed_grfs: Changing source and destination
  numbers, so include INSTRUCTION_DETAIL.

- brw_lower_send_gather: Insert new instructions (scalar register) and
  change sources and other information on existing ones.  So include
  INSTRUCTION_DETAIL and INSTRUCTION_IDENTITY.  Promote to INSTRUCTIONS.

- brw_opt_eliminate_find_live_channel: Can change source, so include
  INSTRUCTION_DATA_FLOW.

- brw_opt_copy_propagation_defs and brw_opt_cse_defs: Both can remove
  instructions, so include INSTRUCTION_IDENTITY.  Promote to
  INSTRUCTIONS.

- brw_opt_saturate_propagation: Instruction can have `sat` modified,
  and operands can have type modified, so include INSTRUCTION_DETAIL.
